READING-GLASS.

Specification of Letters Patent.

Patented Nov, 19, 1912.

' adjustable facilities for steadying the glass while in use, and which will also maintain the glass in usable position with relation to the article under inspection when the hand has been withdrawn from it.-

' I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a perspective of my improved,

reading glass with the legs unfolded or in improved reading glass, with the legs folded other forms of lens.

up or in closed position; Fig. 3 is a fragmentary detail rear view, partially in seiction, of the connection between the leg and the frame, showing the lock for holding the leg in open position; and Fig. 4 is a section on line 11 of Fig. 3.

Similar reference numerals refer to similar parts, throughout the several views.

The reference numeral 1 designates a suitable reading lens, which is conveniently made of rectangular outline, although the principle of my invention is applicable to The lens, 1, is held in a frame comprising the side bars, 2, which are provided with the longitudinal channels, 3, into which extend the sides of the lens, 1, and the end plates, 4 and 5. The end plates are secured to the side bars by screws, 6, or any other suitable means.

To the central portion of the end plate, 5, is secured a suitable handle, 7. Extending substantially at right angles from either end-of the end plate, 4, are short projecscrews, 6, are the legs, 10, which are slotted 'at a point, 11, which comes opposite to the indentations, 9,- upon the short arms, 8. small plate, 12, is provided, which has a projecting portion or pawl, 13, thereon,

legs.

which extends into the slot, 11, upon the legs, 10, and which will extend into the indentation, 9, upon he short arms, 8, when t- IS brought opposite thereto by the swingmg of the legs, 10. In. order to secure the plate, 12, and pawl, 13, in position, a plate, 14, which-is larger than the slots at 11, is secured in front of the legs, 10, to the plate, 12, through the said slots by means of the screw, 15, and a spring, 16, is provided for pressing the projection or pawl, 13, into engagement with the indentation, 9. The sides of the plate, 12, extend slightly beyond the-edges of the legs, 10, and are milled so as to facilitate the disengagementof the projection, 13, from the indentation, 9,

manually, when itv is desired to fold the legs into closed position. The inner corner of the arms, 8, at 17 are rounded so as to permit the pawl, 13, to clear said corner when the legs, 10, are being opened.

The legs, 10, are made of such length that when they are open and in contact with the beokpr paper under inspection it will be in good focus.

It will now be perceived, and especially by reference to Fig. 1, that the user of the glass may move it over the book or paper while the legs, 10, are contactlng therewith.

This will c ntribute largely to the steadiness of the glass and the .eilicieney of the service that may be had from it. It is also possible to withdraw the hand entirely from the glass, when it will be supported by the handle, 7, and legs, 10, in an inclined position, such as is most advantageous for the inspection of the article under it. is not in use,or it is desired to use it without the supporting legs, the legs may be folded, as shown in Fig. 2, in which position they will be entirely out of the way, and the glassmay be put into a case, or in the pocket, or used in any manner in which it could be, if it were not provided with the I do not wish to be held to the specific embodiment of my invention disclosed in the drawings, as it is OlWlOHS thatmany variations therefrom may be made without departing from its spirit or scope.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A reading glass, comprising a lens, a. handle therefor, and legs extendingat sublVh en the glass iro handle therefor, and means for steadying the I glass in use comprising two legs of suitable length, pivotal mountings for said legs, and means for securing said legs in proper position.

I11 testimony whereof, I have hereunto 15 set my hand in the presence of two Witnesses.
